Use Moto as EC2 backend

This tutorial explains moto.ec2‘s features and how to use it. This tutorial assumes that you have already downloaded and installed boto and moto. Before all code examples the following snippet is launched:

>>> import boto.ec2, moto
>>> mock_ec2 = moto.mock_ec2()
>>> mock_ec2.start()
>>> conn = boto.ec2.connect_to_region("eu-west-1")

Launching instances

After mock is started, the behavior is the same than previously:

>>> reservation = conn.run_instances('ami-f00ba4')
>>> reservation.instances[0]
Instance:i-91dd2f32

Moto set static or generate random object’s attributes:

>>> vars(reservation.instances[0])
